How Does a Magnetic Lock Work?

Published on 27th July 2018By Electric Locks

Magnetic locks are considered one of the most secure locks you can have; they are extremely reliable and rarely hacked. In addition, they are quick and easy to install, and they allow for fast access into the building, which is why magnetic door locks are a popular choice for offices, residential and commercial properties.

What is a magnetic lock?

A magnetic door lock is a lock that uses an electric current to produce the magnetic force. Due to the increased strength because of the current, the doors can withstand pressure, so they can’t be forced open without use of the confirmed access method.

How does a magnetic lock work?

Not unlike what you learn about magnetics, magnetic locks work by north and south end meeting and sealing, but magnetic door locks use an electrical current to produce a stronger magnetic force.

Magnetic door locks use an electromagnetic force to stop doors from opening, so they are ideal for security. Mag locks, such as the Deedlock mag locks are made up of an electromagnet and an armature plate. The plate is attached to the door, and the magnetic to the door frame. Depending on the lock chosen, depends on the voltage – and strength – of the electromagnetic force. The rule of thumb is the more expensive the electromagnetic lock the higher the holding force, it can range anything from 250kg all the way up to an impressive 1000kg.

An electromagnetic lock creates a magnetic field when energized or powered up, causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening. As they require power to remain locked, this allows them to be fail-safe, making electromagnetic door locks safe for use as emergency exits. If the power was to go out in a fire via a fire relay or call button, the door would unlock, allowing people to exit the building.

Uses of a magnetic lock

Electromagnetic locks are commonly used in hotels, offices and residential blocks as they are secure, reliable and quick to install, as there are few components.
